Biometric fingerprint recognition and in that vein recognition technology introduction

The 21st century is an era of rapid development of science and technology, new technology, security, people's attention more than ever, our privacy practices through the key to password to IC card process, but at this stage, the most secure and reliable way to secure recognition than biometric identification technology.

Biometric technology is becoming a flourishing field, as the computer industry is an important application direction, is also the most fierce competitive technical direction.

Biometric technology is computerized and optics, acoustics, biological sensors and biological statistics theory and other high-tech means closely, use of the human body's inherent physiological characteristics, (such as fingerprints, facial images, Iris, etc) and behaviors (such as writing, sound, gait, and so on) for the identification of personal identity.

Basis of human biological characteristics of physiological characteristics or behavior patterns can be divided into multiple biometric identification. Physiological characteristics of a hand, fingerprint, face, Iris, retina, pulse, Auricle, etc.; behavior characteristics of a signature, the intensity of the sound, press, etc. According to the different human physiological characteristics, there are already fingerprint recognition, iris recognition, face recognition, PalmPrint identification, voice recognition, vein recognition, brain waves to identify different identification methods.

Because the fingerprint of the biometrics technology started earlier, and with fingerprint recognition system out of the financial, Government, vital sectors, such as airports, more and more appear in intelligent buildings, PC computer and other enterprise-level civil areas, making the fingerprint recognition become the application up, market share, the largest class of biometric technology.

There are statistical data show that in 2005 China biometrics market annual sales of approximately 16.5 million sets, of which more than 96 per cent for fingerprint recognition products. But in reality, there are some fingerprint recognition. When you enter the Office, finger fingerprint access control system by many times, but always can not open the door; fingerprint patterns on one and manual worker fingerprint cannot be identified; the recognition rate is not high, and so on. As a result of fingerprint identification technology environmental requirements are high and the humidity of the fingers, cleanliness, very sensitive, these will affect the recognition results.

Fingerprint recognition technology evaluation criteria mainly judeng rate (FTE), the rejection rate (FRR), error recognition rate (FAR), equal error rate (EER).

Although many fingerprint verification technology provides manufacturers, often claim that their products can meet the targets for FRR < 0.01%, FAR < 0.001%. But from the published academic papers and authoritative test, this index is very difficult to achieve.

Fingerprint identification deficiencies also in several ways:

1. the requirements of the environment is high on the fingers of humidity, cleanliness, etc are very sensitive, dirt, oil, water will not cause identification or recognition results affected;

2. certain people or certain groups of fingerprint features, or even no fingerprints, so hard to Imaging;

3. for dehulling, bruises and other low-quality fingerprint identification difficulties, recognize the existence of the problem, for some hands on table of manual workers and other parts of the special population registration and it is quite difficult to identify;

4. each time you use the fingerprint is the head of the fingerprint on the user's fingerprint impressions, but these fingerprint marks exists is used to copy the fingerprint;

5. the action when the fingerprint recognition requires a high standard;

Compared with these, the vein recognition is effective to avoid the above problem, through the following introduction, we can see that vein recognition have advantages.

Finger vein recognition is a near-infrared radiation on living organisms to irradiation of vein, through the acquisition of the images and make cryptography, authentication technology.

Medical research has proven that the finger vein of shape is unique and stability, that is, each person's finger vein image are not the same, the same person different finger vein image is not the same; the shape of the vein of healthy adults no longer change. This means the vein provides medical fact.

In comparison with the fingerprint recognition technology, it has a vein in the body, copied or stolen is small, the use of psychological resistance is low, the physiological and environmental factors, to overcome the skin is dry, greasy dirt, dust, skin abnormalities, and other factors, the original image from the finger vein is captured to digitize the whole process less than 1 second, and so on, and can be triggered by high accurate recognition rate (admitted false 0.0001% rejection of real 0.01% registration failure rate of 0 per cent) and many other important features that make it highly secure and convenient than on fingerprint recognition technology.

Hitachi has been committed to expanding the application of finger vein authentication, 2002 has been applied to the door lock and access management, 2005 to the ATM and other financial areas of personal certification.

Including entrance guard management, finance, and this information is fields. This will further expand the scope of application to the IT equipment in the field of information security. By expanding the application of finger vein authentication, will become the industry standard for user authentication.

At this stage, there is a vein recognition or the undeniable competitive advantage, in the near future, this advantage will be maintained until the newer and more sophisticated technology and products.

Now, the vein recognition technology is rapidly developing, are gradually achieve greater market space, refers to the vein recognition will be achieved faster development, access to more areas.
